Insert Molding
What Is Insert Molding?
Insert molding is the process of molding plastic around a pre-placed component—such as a metal insert, threaded bushing, or electronic connector—to create a single, integrated part. This technique improves strength, durability, and performance while reducing assembly steps and cost.
At National Molding, we use insert molding to help customers streamline designs, simplify production, and deliver more reliable products across industries.
